Abstract

The aim of this study was to determine in vitro dry matter digestibility (IVDMD) of cocoa pods following treatment of immersing the cocoa pods into different alkaline solution at different length of immersion time. The experiment was carried out in a 5 x 3  factorial  arrangement  according to completely randomized design. The replication for each treatment combination was three giving the total number of experimental units was 45.  The first factor was different alkaline solutions, namely P1: water, P2: rice husk ash solution 10%, P3: coconut shell ash solution 10%, P4: cocoa pod ash solution 10% and P5: NaOH 6%. The second factor was immersion time, i.e. T1: immersion time for 8  hours, T2: immersion time for 16 hours, and T3: immersion for 24 hours. Analysis of variance indicated that alkaline solution, immersion time, and interaction between alkaline solution and immersion time affected (P<0.05) IVDMD of cocoa pods. In conclusion, the IVDMD decreased as the length of immersion time increased. Moreover, the best alkaline solution giving similar result to that NaOH 6% solution was alkaline solution made from cocoa pods ash.

Abstract

Urea Mineral Molases Liquid (UMML) dan biomassa murbei dapat menjadi prekursor biofermentasi dalam sistem rumen. UMML dapat menyediakan nitrogen lepas lambat, mineral larut air dan readily available carbohydrate (RAC), sedangkan biomassa murbei dapat menyediakan RAC, asam amino bercabang, mineral dan vitamin.  Formula UMML adalah larutan yang tercampur dari bahan-bahan yang terdiri atas Urea-kalsium (Ca(urea)4Cl2), molases dan larutan fosfat (fosfat dilarutkan dengan asam organik). Diperlukan jumlah UMML yang tepat dalam ransum sehingga ransum menjadi efisien. Penelitian ini menguji tingkat penggunaan UMML yang efektif mendukung biofermentasi bahan pakan campuran jerami padi dan biomassa daun murbei dalam sistem rumen. Ransum uji terdiri atas jerami padi dan biomassa murbei dengan perbandingan 70:30, yang diaplikasikan tiga perlakuan yakni tanpa penambahan UMML serta penambahan UMML sebanyak 10% dan 20% (v/w). Pengujian dilakukan pada  rumen in vitro. Peubah yang diamati adalah nilai pH, konsentrasi amonia dan VFA,  produksi gas dan tingkat degradasi bahan kering ransum.  Hasil penelitian menunjukkan bahwa penambahan UMML yang terbaik pada fermentasi campuran jerami padi dan biomassa murbei adalah sebesar 10%.

Abstract

Farmers in Enrekang, South Sulawesi typically feed their goats with Gliricidia maculuta as a sole diet. This may cause a problem due to asynchrony of nutrient availability in the rumen,especially the availability of energy and protein, which could lead to poor milk yield in terms ofquantity and quality. The purpose of this research was to study the effect of providing multi-nutrientblock (MNB) on the physical and chemical characteristics of goat milk. Ten Ettawa crossbred goatson the 3rd-4th month of their lactating period were randomly divided into two groups (fivegoats/group). Each group was either fed on Gliricidia maculata/control (ration C, a ration typicallyused by Enrekang farmers for feeding their goats) or fed on C + MNB (CM). MNB was formulatedfrom locally available feedstuff and was provided at the level of approximately 500 g/head/d. Theresults of the study showed that provision of MNB did not significantly (P>0.05) improve milk yield,i.e. 198 and 274 ml/d for C and CM, respectively. The treatment did not significantly (P>0.05) affectphysical characteristics, i.e. pH and specific gravity of the milk. Similarly, provision of MNB did notsignificantly (P>0.05) alter chemical composition, i.e. total solids, crude protein, fat, carbohydrate,lactose, mineral, Ca, and P of the milk.  In conclusion, there was no significant benefit on providingmulti-nutrient block for goats consuming Gliricidia maculuta as a sole diet in terms of physical andchemical properties of the milk, but there was a tendency that provision of MNB may improve yield,crude protein and fat of goat milk.Key Words: Multi-Nutrient Block, Protein of Goat Milk, Fat of Goat Milk, Total Solids of Goat Milk, Gliricidia maculata
